There are many ways to find inexpensive gifts for all members of the family. Garage sales and consignment shops are great ways to find new items for a fraction of the cost of the same item in a retail shop. Also, shopping during the year during sales or after season times will allow you to find things very cheap that are brand new. Discount stores or outlet stores like Bealls Outlet, Ross Dress for Less, TJ Maxx, etc can provide new items for less because they sell close out or overstock items.
A good idea is to use what you are good at to create gifts. If you love to take pictures, offer to take family portraits on location for a friend, your sister or brother, your parents, then give them a copy of the pics edited on CD to do with as they wish. If you are a cook, bake cookies or banana nut loaves for members of your family and friends. Who doesn't like something home cooked. For children, there are so many books, toys, etc that are $10 and under.
Get creative. It's all about having fun.
